A range finding device having a lens holder with two tunnels, and two lens plates mounted in front of the tunnels. Two pins are formed on the front surface of the lens holder, the two pins being positioned on vertical positioning lines externally of the vertical center lines of the two tunnels. Each lens plate has an elongated hole extending in the direction of the vertical positioning line, a pin being inserted in the elongated hole. In a preferred embodiment, each lens plate has four holes formed therein. Two of the four holes are used for coupling with two pins. Of these two holes used for positioning, one is a round hole and the other is an elongated hole.
